identifying a first region and a second region of the image;
identifying by the device a first resolution and a second resolution, the second resolution is a most appropriate resolution
that is identified by calculating the most appropriate resolution for the image according to the following:
MAR =max (H−max([(log2(1/K)],0),0)
where MAR is the most appropriate resolution, H is a maximum resolution, and K is a zoom ratio for display of the image; and
transmitting the image by transmitting, in the following order, the first region in the first resolution, the second region
in the first resolution, the first region in the second resolution, and the second region in the second resolution for progressive
display of the image.
